George - great pics of diff bolts but you lost me. Not too up on Rear-Ends...at least not this kind.

You show two different style bolts. One you show as a Backing Plate to Diff Bolt and the other as a Diff T-Bolt. Am I correct in saying the Tee Bolts are for securing the Backing-plates to the housing or spindle flange? And what about the nut and bolt? Sorry too lazy to pull the tire and hub to find out for myself.

Pictures help dummies like me so please include something as reference. Keep it clean...

Marty the nut and bolt that he posted are for the backing plate to axle flange. These T-bolts hold the rear shock plates on. There are 2 used in conjunction with 2 U-bolts for multi leaf application. The T-bolt goes inboard and the U-bolts go outboard next to the backing plate. There are 4 of these used for the mono leaf springs.

Marty, restoring my axles & wheel studs & thought I would post this picture. One axle had five studs with triangle stamping the other had "F" stamping on the studs.Studs are all same length, "F" studs have slight taper at the start of the thread for maybe 1/16". All were black phosphate finish before glass beading.Both axles seem original but I don't know for sure. Maybe others can post what they have seen. George.

George - I think its safe to assume this thread began about the same time you started restoring your car. I also think its safe to assume I'm not the only one that feels fortunate you are sharing this information. Kudos my friend and please keep the pics and fastener info coming! I'll add all of them to an updated version soon.

Marty, just a thought, that's all. We all know there are a lot of head markings but it might make life easier if we note headmarkings on specialized screws/bolts. Good examples are what George just reported on, i.e. "wheel studs" etc.. I remember the triangle on the end of some of our studs but will have to check them out. Some head markings will be spread among several types/sizes of screws/bolts but some of these special ones are just that, special.Thoughts?
